Daya Mata, born Rachel Faye Wright, was the third president and religious leader of Self-Realization Fellowship/Yogoda Satsanga Society of India (SRF/YSS). SRF/YSS is the only spiritual organization founded by her guru, Paramahansa Yogananda, to disseminate his teachings. She was president of SRF/YSS for over 55 years until her death in 2010.

Self-Realization Fellowship (SRF) is a worldwide religious organization founded in 1920 by Paramahansa Yogananda, the Indian guru who authored Autobiography of a Yogi. Before coming to the United States, Yogananda began his spiritual work in India in 1917 and named it Yogoda Satsanga Society of India (YSS). He came to the West in 1920 and in 1925 established SRF's headquarters at Mount Washington, Los Angeles, California. Before his return visit to India in 1935, he legally incorporated SRF in the United States, designating it as the only organization to carry on his work – to care for and disseminate his teachings.
